@markap14 I will add descriptions to the annotations for the processors you
mentioned. Thanks for the extra info! We can do additional PRs to add more
descriptions as needed, but I think the default descriptions are good to at
least mark the current processors that might cause resource issues.
As @joewitt mentioned, the annotation doesn't need to be used just to
convey that a component might use a lot of a particular resource. It can also
include descriptions on how to best utilize the resources, or indicate that the
component uses very little of a type of resource and can parallelized to a high
degree without degrading system performance. I can agree that currently, there
aren't many components that would use the DISK or NETWORK SystemResource type
when referring to how a single flowfile would affect them, but there may be in
the future. I think it's a good idea to keep all four types in the
enumeration.
